jaxrts.ion_feature.q_DebyeHueckelChapman2015

jaxrts.ion_feature.q_DebyeHueckelChapman2015(k: Quantity, kappa: Quantity, Z_f: Quantity | Array) → Quantity[source]

Calculates the Debye Hückel screening presented in [Chapman et al., 2015], eqn (5).

Parameters:

k (Quantity) – Length of the scattering number (given by the scattering angle and the energies of the incident photons (unit: 1 / [length]).
kappa (Quantity) – The inverse sceening length, units of 1 / [length]
Z_f (Quantity, jnp.ndarray) – The ionization / mean charge state of the ions. Should be one entry per ion considered.

Returns:

q(k) (Quantity) – The screening charge. Has the shape (n, m), where n = len(Z_f) is the number of ions, and m = len(k).
